I had the runs, mucus and bloating for 10 weeks following what I thought was gastro after contact with my grandchild (who had a virus). GP did some blood and stool tests and said his impression was of IBS. I don\t suffer any stress! So I tried lactose free and after 2 weeks the symptoms have completely resolved. My 30 year old daughter has been lactose intolerant since aged 15 and so I knew what to do. My questions are- 1. anyone else had this in their 60s - 2. How long should I wait before trying lactose/milk products again? - 3. Am I likely to improve or is this permanent now?
